Re: [Libguestfs] [PATCH 0/4] Allow QEMU if=... (block device emulation) to be overridden

The background to this is that virt-v2v needs to boot the appliance with a specific block device emulation (eg. IDE, not virtio), because when it runs mkinitrd, mkinitrd will assume that the block devices available in the appliance are also the ones which apply at guest boot time. There's no way to override this assumption in mkinitrd (particularly in the old mkinitrd versions that shipped with RHEL3/4/5), so we have to change libguestfs to allow this instead. Rich.
